Steps
Open the Corps Locks portal at https://ndc.ops.usace.army.mil/ords/r/lpms/corps-locks/home.
Navigate to the Lock Queue Flotilla Report to see vessels currently waiting at a specific lock (updated roughly every 15 minutes, last 30 days).
Navigate to the Lock Status Report to check whether the lock is fully operational, restricted, or closed.
Cross-reference the River at a Glance Report for a 24-hour map/table view of nearby vessel traffic if planning a longer transit.
Advise marina customers or harbormaster staff of expected delays before they depart toward a congested or degraded lock.
Known gotchas
This is a public Oracle APEX web application (HTML reports), not a documented JSON/REST API — an agent needs to parse rendered report pages, and a linked 'Data Web Services' page could not be confirmed to expose a stable programmatic endpoint in this research pass.
This system covers inland river/waterway locks (USACE navigation infrastructure), not coastal marina operations directly — only relevant to marinas near lock-controlled waterways.
